You could do both: That's a cool thing about Enclave Watch. It features an interchangeable strap. You can swap straps around without any tool (I don't own one yet, just my guess from the description).
I ordered an additional nylon strap, and would use the 3-color strap as my daily driver, and swap to a leather band when I need to suit up.
Why buy watches for each occasion? Buy it for the time!
